Centralized active reconfigurable intelligent surface: Architecture, path loss analysis and experimental verification
Changhao Liu, Fan Yang, Shenheng Xu +2
Reconfigurable intelligent surfaces (RISs) are promising candidate for the 6G communication. Recently, active RIS has been proposed to compensate the multiplicative fading effect i…
A Beam-Steering Reflectarray Antenna with Arbitrary Linear-Polarization Reconfiguration
Changhao Liu, Songlin Zhou, Fan Yang +2
This work presents a beam-steering reflectarray antenna that achieves arbitrary linear polarization (LP) reconfiguration. This antenna employs a dual-circular polarization (CP) rec…
Transmission efficiency limit of single-switch and cascaded reconfigurable transmitarray elements
Changhao Liu, Fan Yang, Shenheng Xu +1
Reconfigurable transmitarray antennas (RTAs) are rapidly gaining popularity, but optimizing their performance requires systematic design theories. In particular, establishing a per…
Reconfigurable Metasurface: A Systematic Categorization and Recent Advances
Changhao Liu, Fan Yang, Shenheng Xu +1
Considering the rapid progress of theory, design, fabrication and applications, metasurface (MTS) has become a new research frontier in microwave, terahertz and optical bands. Reco…
Active RISs: Signal Modeling, Asymptotic Analysis, and Beamforming Design
Zijian Zhang, Linglong Dai, Xibi Chen +4
Reconfigurable intelligent surfaces (RISs) have emerged as a candidate technology for future 6G networks. However, due to the "multiplicative fading" effect, the existing passive R…
A Radiation Viewpoint of Reconfigurable Reflectarray Elements: Performance Limit, Evaluation Criterion and Design Process
Changhao Liu, You Wu, Songlin Zhou +4
Reconfigurable reflectarray antennas (RRAs) have rapidly developed with various prototypes proposed in recent literatures. However, designing wideband, multiband, or high-frequency…
